ImplementationContext¶

class sentaku.ImplementationContext(implementations, implementation_chooser=NOTHING, strict_calls=False)¶

maintains a mapping of implementation-identification to implementations, as well as the list of currently availiable Implementations in the order of precedence.

Parameters:	implementations (collections.Mapping) – the implementations availiable in the context a mapping of implementation-identification to implementation default_choices (optional list) – the implementations that should be used by default in order of percedence

context¶

alias for consistence with elements

classmethod from_instances(instances, **kw)¶

utility to create the context

by passing a ordered list of instances and turning them into implementations and the default choices

impl¶

the currently active implementation

root¶

alias for consistence with elements

use(*args, **kwds)¶

contextmanager for controlling the currently active/usable implementations and their order of percedence

Parameters:	implementation_types (implementation-identification) – the implementations availiable within the context frozen (bool) – if True prevent further nesting

Application Elements¶

Application elements are subclasses of sentaku.Element. They describe single Elements of Applications

Elements on a abstract perspective Refer to Collections, Entries and sets of actions.

Depending on implementation they can be listings, forms, rest collections/data entries, or file contents.

class sentaku.Element(parent)¶

Base class for all application elements

Parameters:	parent (Element or ImplementationContext) – controlling object of the element which is either a context or a surrounding element

Contextual Methods¶

class sentaku.ContextualMethod¶

descriptor for implementing context sensitive methods and registration of their implementations

class Example(Element):
    action = ContextualMethod()
    @action.implemented_for("db")
    def action(self):
        pass

   @action.implemented_for("test")
   def action(self):
       pass
